Really? I googled a bit for it some weeks ago and found this patch

 http://www.uwsg.iu.edu/hypermail/linux/kernel/0303.3/1548.html

that looked pretty simple. Haven't applied though, because I rarely use
the one box I have with PCMCIA sockets and I don't know enough kernel
stuff. 

Waiting for 2.7 for this would really really suck. One thing we should
then is to try to do what cardmgr and cardctl does and build our tree
this way if at all possible (I've would have no clue on how to map class
devices to such bus devices though).

But in the, unlikely, event that I have two 16-bit PCMCIA networking
cards they will both merge net.* stuff on the same fakeroot device and
one will overwrite the other, right?

Cheers,
